causeway To all whom itmag concern: 1 I

Be it known that I, EDWARD Enronson, a subject of theK ing of:Swed'emand. a resident of Lynn, in the county of Essex and State oflilassachusetts, have invented certain new and useful Improvements inMovableGuards for Sewing-Machines, of which the following is aspecification.

This invention relates to sole sewing machines and particularly to meansfor protecting the work from being injured or soiled duringtheoperationof the machine,

' and has for its object the provision of means for protectingtheworkfrom the operating parts of the machine. I a

This inventionbonsists in providing the awl supporting member with aguard adapted to be moved laterally therewith 'in contact with the frontface of the work support during the feeding operation.

The invention further consists in certain novel features or"construction and arrangement of parts which will be fully understood byreference to the description of the drawings and to the claimshereinafter given.

Of the drawings: Figure 1 represents a front view of a machine embodyingthe principles of the present invention, and Fig. 2 represents avertical section of the same, looking to theright of Fig. 1.

Similar characters designate like parts throughout the figures of thedrawings.

The invention is illustratedas applied to a sole-sewing machine similarto that shown and described in application filed by. Lawrence E. Johnsonand myself, May 19, 1913, Ser. No. 768,671, to which reference may bemade for the complete operation of the machine.

In the drawings 20 is the base of the ma chine adapted to be secured toa column and having the end frames 21 and 22 provided with bearings fora revoluble shaft 23. The revoluble shaft 23has the driving, wheel 24secured to one end thereof, while to its opposite end is keyed the camdisk 25. Interposed between the side frames 21 and 22 and keyed to theshaft23 is the cam disk 27. The cam disks 25 and 27 are adapted tooperate various mechanisms necessary for the proper operation of themachine, all of which have been fully illustrated and described in theapplication 768,671, hereinbe sp i va ion of etter a n Application filedJuly 20, 1914. Serial No. 852,102.

, MOVABLE en ma R SEWING-MACHINES- Pate Aue- 1 1915- nisms form no partof the present invention they are not herein described.

To the innerside of the side frame 21 is secured the work support 28which may be of any well-known construction. The side frame21 has alsoformed upon its inner face a race 30' for the shuttle 81 which is drivenin any well-known manner. The frame 22 is provided with two bearings inwhich reciprocate two parallel studs or pins 61 mounted upon 'a movableframe 62. This frame haspivoted to the lower end thereof at 63 anoscillating slotted lever 64:, the lower end of which is provided with aroller 65 extending into a cam path 66 in the periphery: of thercam disk27 In the slot 67 of the lever 64 is a fulcrum block 68 pivotallymounted in'a forked member 69 having a shank 70 extending through astraight slot 71 in the frame 22, and also through a slot 72 in ahandlever 73 pivoted at 74 to the end fra1ne 22. It is obvious that when thethe free movement of the forked member 69 "lengthwise of the lever 64:without binding thereon. By means of the handle 63 the position of thefulcrum block 68 may be changed at will to secure any desired degree ofspeed. The frame 62 has mounted thereon the shaft 80 carrying the needleguide 88. Rotatable about the axis of the shaft 80 is a needle supportcarrying the needle 84. The needle support 85 has a gear segment 86formed thereon through which oscillatory movement may be imparted to theneedle and the awl 91 also secured to said needle support 85. Themachine is also provided with the looper 126 operated by suitablemechanisms which form no part of the present invention. The needle andawl support move laterally with the frame 62 and when the awl is in thework the said a leaves the work the frame 62 is returned to its normalposition before the awl again moves forward to pierce the work.

Secured to the' frame 62 is a guard 100 which 'is curved outwardly andin front of the work support 28 as is clearly indicated in Figs. 1 andv2of the drawings. When the frame 62 is moved laterally to feed the j workthe guard 100 is interposed between the work and the work supportandmoves with thelatter, thereby preventing the work from being injuredby contact with the work support and also keeping the work out of thepath of the operating parts of the machine adjacent thereto such as thelooper 126, the awl 91, and the needle 84.

This guard constructedas shown and described not only prevents the workfrom being injured or soiled but also prevents the workfrom assumingsuch a position as to interfere with the operation of themachine.Byproviding a guard of this characterand attaching it to the workfeeding devices the feedingvof the work is greatly facilitated, asduring the feeding operation the work would be free from frictional"contact with any stationary part of the machine.

It is believed that the operation and many advantages of a guard of thecharacter described will be fullyapparent without fur- 1 Copies of thispatent may be obtained for ther description.

Having thus described my invention, I claim:

1. In a sole-sewing machine, the combination of a work supportf needleand awl actuating mechanism; a member movable horizontally to feed thework on said sup port; and a guard secured to said member and movabletherewith to protect the work during the operation of the machine,
